In this we have the opposite extreme of Realism. If the Realist went too far in affirming the objective reality of his conception, the Nominalist erred on the other in overlooking its subjective reality as a mode or state of the mind, and reducing it to a mere name.
Dispute becomes theological.—The dispute now, unfortunately, but almost inevitably, became theological. The Realist accused the Nominalist of virtually denying the doctrine of the Trinity, inasmuch as, according to him, the idea of Trinity is only an abstraction, and there is no Being corresponding to that idea. To this, Roscelinus replied, with at least equal force and truth, that on the same ground the Realist denied the doctrine of divine unity, by holding a doctrine utterly incompatible with it. Roscelinus, however was defeated, if not in argument, at least by numbers and authority, and was condemned by council at the close of the eleventh century.
Rise of Conceptualism.—It was about this time, that Abelard, pupil of Roscelinus, proposed a modified view of the matter, avoiding the extreme position both of the Realist and the Nominalist party, and allowing the subjective, but not the objective reality, of general ideas. This is substantially the doctrine of Conceptualism. The general abstract idea of man, rose, mountain, etc., has indeed no existence or reality as an external object, nor is there among external objects any thing corresponding to this idea; but it has, nevertheless, a reality and existence as a thought, a conception of my mind.
Prevalence of Realism during the twelfth and thirteenth Centuries.—The doctrine, as thus modified, gained some prevalence, but was condemned by successive councils and by the Pope. Sustained by such authority, as well as by the names of men greatly distinguished for learning and philosophy, Realism prevailed over its antagonists during the latter part of the twelfth and the whole of the thirteenth century. The fourteenth witnessed again the rise and spread of the Conceptualist theory, under the leadership of Occam. The dispute was bitter, leading to strife and even blood.
Later History of the Discussion.—In the seventeenth century we find Hobbes, Hume, and Berkley advocating the doctrine of the Nominalists, while Price maintains the side of Realism. Locke and Reid were Conceptualists, Stewart a Nominalist.
CHAPTER II.
THE ANALYTIC PROCESS—REASONING.
Relation to the Synthetic Process.—We have thus far considered that form or process of the reflective faculty, by which we combine the elements of individual complex conceptions, to form general conceptions and classes, on the basis of perceived agreements and differences. This we have termed the synthetic process. The divisive or analytic process remains to be considered. This, as the name denotes, is, so far as regards the method of procedure, the opposite of the former. We no longer put together, but take apart, no longer combine the many to form one, but from the general complex whole, as already formed and announced, we evolve the particular which lies included in it. This process comprehends what is generally called analysis, and also reasoning.
In discussing this most important mental process, we shall have occasion to treat more particularly of its nature, its forms, and its modes.
